[EN] The effect of two caffeine preparations was studied on
the reproductiva parameters (conception rate, litter size and weight, sex
ratio of the offspring) in rabbits. In the experiment, Al was carried out on
78 lactating females (divided into 3 groups). Group A was inseminated
with diluted semen containing 1 mg Coffeinum Natrium Benzoicum per
millilitre, group B was inseminated with diluted semen containing 1 mg Coffeinum Natrium SaHcylicum per millílitre, group e was inseminated
with caffeine free diluted semen. The caffeine salicylate improved the
conception rate (73.08, 100, 71.88 %) (P<0.01). There was no effect of
caffeine on the litter size and weight. In the treated groups the rate of
new-bom male rabbits increased significantly (65.97 and 63.06 vs.
49.26 %) (P<0.01).[-]
